Question: I am trying to submit a CTR for my company but it's asking for TFN. I don't have a TFN for my company. How do I obtain this?

Answer: Is this a new company?, and you have an on-going application for a TFN?

Must apply for a TFN, you cannot proceed without TFN via platform. You can still ldoge through paper return, but should have a record that you applied for it.
